DEPARTMENT REPORTS. 157 



KEJH)irr OF THE DIOPAKTMENT OF ZOOLOGY AND 



rilVSlOLOGY. 



To the President, 



Michigan Agricultural College. 



Sir; 



I have the honor to submit the following report of the Department of 

 Zoology and Diysiology for the year ending June oO, 1022. 



The resignation of Assistant I'rofessor ^\n'ne E. LeHoy during the 

 summer of 1921 left a vacancy in the staff which has not been filled. 

 Dr. H. E. Johnson and Dr. O. A. Taylor, both of the Veterinary Division, 

 were assigned temporarilv for work in tlie physiological laboratory aud 

 have continued to give more or less lielp through (lie year. AVith these 

 excei)tionis tliere" hais been no change in the personnel of the department. 

 The following data will give some idea of the kind aud amount of class 

 work each term : 



Fall term. Two classes in zoology 82 students 



Two classes in physiology . . . 150 students 

 Four classes in geology 84 students 822 



Winter term. Three classes in zoology 59 students 



Three classes in physiology . . . 100 students 

 Three classes in geology 69 students 228 



Spring term. Three classes in zoology 57 students 



Two classes in physiology ... 29 students 



Two classes in geology 42 students 128 



Summer School (1921). 



Two classes zoolog;^' 13 students 13 



Total number of students 691 



Summary: Total number of classes during the year, 26; elective, 11 ; 

 optional, 1; required, 14. Number of students taking elective:s, 138; 

 optional, 26; required, 527, Average number in required classes, 37.6; in 

 elective classes, 12.5. 



The marked inequality in the number of students handled in the differ- 

 ent teraiiS is largely due to the change in the Home Economics curriculum 

 which required the repetition of some of the physiology previously 

 dropped from that course and now restored. Probably such a congestion 

 will not occur again. 



Eighteen students elected Applied Science work in zoology in the fall 

 term and thirteen of these carried it through the year. 



It seems worth while to note the fact that although the department 

 is now offering twice as many courses as five years ago, there has been 

 little change in current expenses and no increase in the teaching force. 

 Naturally this cannot continue indefinitely, especially if the Applied 

 Science course developes as expected.
